According to a recent post to nin.com, Trent Reznor confirms that not only is Dave Grohl guesting on the upcoming Nine Inch Nails album Bleedthrough, but he plays on fifteen of the twenty tracks currently being considered for release. Reznor tapped Grohl to achieve his vision of “powerful live drumming” and credits the drummer with bringing the tracks “alive in a ‘better-than-i’d-even-hoped-for’ type way.”http://www.nin.com/access/index.html
